Time Spiral

The Time Spiral was a mysterious phenomenon located in the Time Vortex. The Time Spiral was located somewhere near the end of the Humanian Era.

The Time Spiral could rip apart a TARDIS and anyone inside if it came too close. To deal with this risk, each TARDIS had a device fitted that caused it to materialise any time it came too close to the Time Spiral. However, the Doctor removed his at some point.
